FREDERICK CHARLES REID AND THOMAS l'rAYLoR, or VANCOUVER, BRITISH COLUMBIA, CANADA. Y I A HOSE-UN COUPLING DEVICE.

Specification of Letters Patent. Patented Feb. 15, 1921.

Application filed Ju1y'9, 1920. Serial No. 394;869.

1 0 all whom) it may concern Be it known that we, FREDERICK CHAnLns REID and THOMAS TAYLOR, both subjects of the King of Great Britain, and residents, respectively, of the cityof Vancouver and the municipality of Burnaby, in the Prov ince of British Columbia, Canada, have invented certain new and useful Improvements in Hose-Uncoupling Devices, of which the following is a specification.

Our invention relates to improvements in hose uncoupling devices, and the object of our invention is to provide a device of this nature by means of which the air brake hose between railway cars may be automatically uncoupled coincidently with the uncoupling of thecar coupler lock in a simple, practical, and eflicient manner by an operator standing on the outside of the cars, thus eliminating entirely the element of personal danger and at the same time avoiding the risk of breaking or tearing the hose which is always present when the same is uncoupled by pulling it apart by the operation of the cars themselves.

We attain this object by the construction illustrated in the accompanying drawing in which- Figure 1 is a side view illustrating the practical application of our invention.

Fig. 2 is a perspective view of the de vice.

Similar figures of reference indicate similar parts in the views.

1 indicates the car coupler lock, as found in railway cars at the present time, the pin 2 of which is withdrawn when uncoupling the look by the operation of the lever 3 in an upward direction, the lever being actuated by means of a handle 4:. 5 indicates the air line found at the ends of the car, the ends of the air line of coupled cars be ing connected by the air brake hose 6, which as is well-known, consists of two sections coupled at the center. Hitherto it has been the common practice when uncoupling the cars to part the hose by a man ste jping.

between the cars to uncouple it by rand, which 18 a dangerous operation, and it has also been the practice to part the hose by,

pulling the cars apart by the engine, which frequently breaks and tears the hose, involv ing expense for new hose or repairs which adds considerably to the cost of railway operation.

To prevent "personal danger on the one hand and'to eliminate'the damage to the hose on the other we secure to the lever 3 at a suitable point thereon a bracket 7 having an opening 8 through which extends the free end of a lever 9 the opposite endof which is pivotally connected to the end of the car on the pin 10. To the free end of the lever 9 is secured a chain 11 the opposite end of which is passed through a pul- 'ley 12 carried by thecoupling end of one hose section and secured to the hose at its opposite, or car end, as indicated at 13 in Fig. 2. The length. of the chain is such that it will be taut when the hose is 0011- pled in operative position, as shown in Fig. 1.

It will now be seen that on raising the handle l to raise the lever 3 to withdraw the coupler pin the lever 9 will 'be swung upwardly, thus tightening the chain 11 and exerting sufficient strain thereon to part-the hose coupling 14- and separate the hose section .6 of the one car from-the section 6 of the other car, the eiiectbeing to double up the hose automatically in substantially the same manner as it is doubled up manually by an operator between the car when the cars are uncoupled in this fashion. It will, of course, be understood that there is one such device as that above described for each hose section with which the end of each car is provided, as shown in Fig. 1.

From the foregoing it will be evident that we have devised a simple and practical air hose uncoupling means which is of great utility and convenience and enables con- 'siderable economy to be effected in train operation.

What we claim as our invention is 1. The combination with the coupled air brake hose sections of railway cars,of means for uncoupling said sections, comprising a lever fulcrunied on a car end, a pulley mounted 011 the outer end of the car hose section, a flexible connection extending from the free end of the lever through the pulley and secured to the inner end of thehose section and adapted to be tightened by the raising of the free end of the lever, and means for operating the lever.

.2. The combination with the coupled air brake hose sections of railway cars, of means for uncoupling said sections, comprising a lever fulcrumed- 01 a W r- Pulley (.110

ing adjacent the outside of the car by means of which said lever may be operated.

3. The combination with coupled railway cars, couplersand uncoupllng rods therefor,

and the coupled air brakehose sections thereof, of means for uncoupling said hosesect ons colncidently with the uncoupling of the couplers,; comprising a slotted bracket secured to the coupler uncoupling rod of one car, a lever passed through the slotin said bracket and fulcrumed at one endon the car end, a pulley mounted onthe, outer end of theqcar hose section, and afiexible connection extending from thefreeend oi the lever through the pulley and connected to the inner end of the hose section, said connection being" adapted to be'tightened by the raising 01" the free end of the lever through'the operation of thesaid coupler uncoupling rod when uncoupling the cars.

4:. The combination with a car coupler, a coupled air hose line and a car-uncounllng device including an uncoupling lever, of

Vmeans for uncoupling the air hose simultaneously with the uncouphng of the car comprisinga bracket carriedby said lever, a second lever passmg through sa d bracket and pivotally secured at one end, and a flexible connectlon extending between the freev end of said leverand said air line. a
